Running Rich/ loss of power
 

Can anyone please help me?
I've recently replaced my engine with a used engine two days ago and now it’s running very rich and has a loss of boost. When I start the car it idles slightly erratic and has a rich smell of fuel. If I drive the car normal it's fine, but if I put my foot down there would be a huge loss of power.

Sounds like the map sendsor isnt hooked up.

And before I get any comments, It really does sound like its the map sensor.
